Întreținere și îngrijire, amenajarea acvariului

The optimal tank sizes for a small flock of these fish start at 80 liters. In the design, it is recommended to use a sand and gravel substrate, several snags and hardy plants (anubias, bolbitis, etc.). Since Rasbora Dorsinota comes from flowing waters, the movement of oxen in the aquarium is only welcome.

The fish needs high quality water and does not tolerate its pollution well. To maintain stable conditions, it is necessary to regularly remove organic waste (food remains, excrement), weekly replace part of the water with fresh water by 30–50% of the volume, and monitor the values ​​of the main hydrochemical indicators.

Comportament și compatibilitate

A peaceful schooling fish, compatible with other non-aggressive species of comparable size. The content in the group is at least 8–10 individuals, with a smaller number they can become overly shy.

Creștere / reproducere

Like most cyprinids, spawning occurs regularly and does not require special conditions to be recreated. The fishes scatter their eggs in the water column and no longer show any parental care, and on occasion they will eat their own offspring. Therefore, in the general aquarium, the survival rate of fry is extremely low, only a few of them will be able to reach adulthood if there are enough dense thickets of small-leaved plants in the design where they could hide.

In order to preserve the whole brood, separate spawning tanks with identical water conditions, with a volume of about 20 liters and equipped with a simple airlift filter with a sponge and a heater, are usually used. No lighting system required. With the onset of the mating season, the eggs are carefully transferred to this aquarium, where the juveniles will be completely safe. The incubation period lasts 18-48 hours depending on the water temperature, after another day they begin to swim freely in search of food. Feed with specialized micro food or brine shrimp nauplii.
